CVE-2023-20198 PoC — Cisco IOS XE Software 安全漏洞

Title:Cisco IOS XE Software 安全漏洞 (CVE-2023-20198)
Description:Cisco is providing an update for the ongoing investigation into observed exploitation of the web UI feature in Cisco IOS XE Software. We are updating the list of fixed releases and adding the Software Checker. Our investigation has determined that the actors exploited two previously unknown issues. The attacker first exploited CVE-2023-20198 to gain initial access and issued a privilege 15 command to create a local user and password combination. This allowed the user to log in with normal user access. The attacker then exploited another component of the web UI feature, leveraging the new local user to elevate privilege to root and write the implant to the file system. Cisco has assigned CVE-2023-20273 to this issue. CVE-2023-20198 has been assigned a CVSS Score of 10.0. CVE-2023-20273 has been assigned a CVSS Score of 7.2. Both of these CVEs are being tracked by CSCwh87343.

# Simple-Ansible-for-CVE-2023-20198
This is a very simple playbook to detect and disable http/https server to prevent the vulnerability.


## Getting started
Simply use the Cisco Always on Sandbox to test example

1. Log into sandbox router and turn on http/https server

```
ssh developer@sandbox-iosxe-recomm-1.cisco.com

pass=lastorangerestoreball8876
```

```
conf t
ip http server
ip http secure-server

```

2. Run the http.yml playbook to determine the state of the config and to disable Http/Https server

The syslog output will be empty if the sandbox router hasn't been exploited.

3. Run Playbook again
This time it should skip the third task becuase of the conditional
